Weatherby Vanguard
I know nothing about the new Model 70's; that said, I bought a Vanguard Synthetic( the $399 one) and have been amazed with its performance. The only change that has been made in this rifle is a trigger spring. That made all the difference in the world.The trigger now breaks cleanly at 2.5lbs.
With my hand loads it shoots cloverleafs at 100yds and is consistantly sub MOA at 200yds.
I have never been sorry that I chose Vanguard.
GOOD LUCK and GOOD SHOOTING!!!
